OE correct oil drain plug
 

Anybody know which vendor sells the correct oil drain plug for the SL55 .
I bought a number of them but they have none of the correct sealer on the threads.
Can't remember who I bought these from and don't want to make the same mistake.
Made the same mistake ordering cam cover gaskets that weren't OEM and had to do the job twice.
Who should I deal with to guarantee correct OEM Mercedes parts ?

Dear astonished----go to any MB dealer or any MB dealer that have an online parts operation like "Skyland"

Thanks, Pluto
